WebJul 17, 2008 · IEEE switch sends IEEE STP BPDUs to IEEE multicast MAC address and those BPDUs are processed by VLAN 1 (CST) STP instance in the Cisco switch. PVST+ side (Cisco switch) sends untagged IEEE STP BPDUs corresponding to VLAN 1 (CST) STP to IEEE MAC address across the link. This is done for the purpose of joining the local … WebSara, think of CST region as actually spanning the entire network. Loops in that network are eliminated according to normal STP rules. If CST-only region have some loops, they will be eliminated as part of that calculation. And as switches in that region don't talk any other STP instances, that loop-free topology remains unchanged.

This document describes the features and configurations for the Multiple Spanning Tree Protocol (802.1s). See more Multiple Spanning Tree (MST) is an IEEE standard inspired from the Cisco proprietary Multiple Instances Spanning Tree Protocol (MISTP) implementation. This table shows the support for MST in various Catalyst … See more As previously mentioned, the main enhancement introduced by MST is that several VLANs can be mapped to a single spanning tree instance. This raises the problem of how to determine which VLAN is to be associated … See more This diagram shows a common design that features access Switch A with 1000 VLANs redundantly connected to two distribution Switches, D1 and D2.
